potential of 3,4-diamino-2-(methylthio)-1-naphthonitrile for the construction of different class of highly functionalized fused polycyclic N-heterocycles, such as 3H-naphtho[1,2-d]imidazoles, benzo[f]quinoxalines and 3H-naphtho[1,2-d][1,2,3]triazoles. 2-(1-Cyano-2,2-bis(methylthio)vinyl)benzonitrile also provides arylated naphthalenes and carbazole depending on use of functionalized 4-nitrotoluenes as
我们已经开发出一种新的,无金属的方法,该方法可通过2-(1-氰基-2,2-双(甲硫基)乙烯基)苄腈与二(1-氰基-2,2-双(甲硫基)乙烯基)苯甲腈的反应合成3,4-二氨基-2-甲基硫烷基-萘-1-甲腈在碱性条件下还原硝基甲烷,然后还原硝基。我们探索了3,4-二氨基-2-(甲硫基)-1-萘腈的合成潜力,可用于构建不同种类的高度官能化的稠合多环N-杂环,例如3 H-萘[1,2- d ]咪唑,苯并[ f ]喹喔啉和3 H-萘[1,2- d] [1,2,3]三唑。2-(1-氰基-2,2-双(甲硫基)乙烯基)苄腈还根据官能化的4-硝基甲苯作为碳负离子源的用途提供芳基化萘和咔唑。通过单晶X射线技术证实了某些化合物的结构。
